A large-scale study on the impact of open access has recently been released, finding that OA papers have a 50 percent greater citation advantage than papers published in subscription-based journals.

The analysis of more than three million papers determined that a journal’s move toward open access publishing is necessary to retain relevance in the field. Additionally, further results point to the face that traditional subscription-based journals will lose their relevance for researchers and governments if they continue to block access to research via paywalls.

This from Digital Journal:

The new research also shows that the widely held belief that open access papers have a greater impact due to them being available earlier than their commercially published versions is not consistent with the large-scale data collected by 1science. In fact, based on a tie series comprising more than 17.4 million papers published between 2000 and 2015, it is clear that open access still suffers from the effect of embargoes enforced by traditional publishers who maintain that they require that delay to keep the subscription model alive.

Many scientists believe we’re at the tipping point of our energy technology future. With the advancement of new, alternative energy sources, some are left to wonder what will happen to the energy landscape as a whole.

While nuclear power has energized much of the world over the past 50 years, the establishment of new nuclear power plants has been nonexistent in recent times in light of other alternatives such as solar and wind. Now, with California phasing out its last nuclear power plant in Diablo Canyon, many are left to wonder just what role nuclear will play in the future of energy.

A turning point

During the oil crisis of the 1970s, global conversations about the future of energy production began to hit the mainstream. If fossil fuels don’t warrant consistent dependency, how would the U.S. power future generations? The answer: nuclear.

“At that time we were thinking we’d build up these nuclear power plants everywhere and they would provide free electricity because it would just be too cheap to meter,” ECS Secretary Jim Fenton previously told ECS.

The thought was nuclear could provide such cheap and plentiful amounts of energy that not only would it be free to the consumer, but there would be an overproduction. This encouraged new research in devices such as flow batteries to store this excess energy.

But those expectations turned out to be wrong.

Biomedical innovations have helped shape the world of modern medicine. From pacemakers to auto-dispensing medications, advances in medical technology have revolutionized the world we live in.

But what happens when some of these devices need to be removed?

That’s where “transient electronics” come in. The concept behind this new technology is that rather than removing medical devices through surgery, scientists could simply develop the device so it could just disappear when the time is appropriate.

The latest development in transient electronics comes from Iowa State University, where researchers have made a breakthrough in the development of a dissolving battery that could power these disappearing devices.

The lithium-ion battery can deliver 2.5 volts and dissipate in 30 minutes when dropped into water. The power generated from the battery could power a desktop calculator for about 15 minutes.

New materials can change their appearance and quickly revert to their original state, taking inspiration from squid and jellyfish.

Researchers believe the materials could have applications in smart windows (allowing users to block light with the push of a button), display optics, and encryption technology.

“There are several marine animals that can very smartly and actively alter their skin’s structure and color,” says Luyi Sun, co-author of the study. “In this work, we follow two examples, squid and jellyfish respectively, to create different mechanical responsive devices.”

This from the University of Connecticut:

They began with a thin, rigid film, and then attached a thicker layer of soft, stretchable elastomer. When the layers are joined and stretched, the rigid layer develops cracks and folds. As this layer is stretched, the cracks and folds grow in size in proportion to the force exerted. As a result, the surface becomes rough and scatters the light that passes through, thereby changing the material’s transparency.

ECS member and director of the Princeton Institute for Science and Technology of Materials (PRISM), Craig Arnold, recently sat down with Princeton University to discuss the current and future potential of materials science.

Arnold and his research group at Princeton focus on materials processing and fabrication, with applications in energy, optoelectronics, sensing, and nanotechnology. Applications of this research touches the frontiers of technology, pushing boundaries on optimizing grid level storage for alternative energy and cutting-edge optical devices.

In the interview, Arnold discusses core components of materials science, his favorite materials, and explains how materials science has become the bass player in the band.

Nissan is taking a big step toward eco-friendly transportation with the development of their new solid oxide fuel cell vehicle.

The science behind the vehicle, which the car company has branded e-Bio Fuel-Cell, uses bio-ethanol fuel to generate electricity through SOFC technology. Nissan states that sugarcane, corn, and soy can all be used as means of fuel – resulting in a carbon neutral cycle when the car hits the road.

The company expects the vehicle to be ready for commercial purchase as early as 2020.

A team of researchers from the National Renewable Energy Laboratory, in collaboration with a team from Shanghai Jiao Tong University, has developed a method to improve perovskite solar cells – raising both efficiency and reliability levels while make them easier to produce.

Perovskite cells have become one of the more promising technologies in the future of energy. In 2010, the young technology functioned at under 4 percent efficiency. Fast-forward to 2016, and researchers and showing efficiency levels of upwards of 20 percent.

However, it’s been difficult to produce these cells and the lack of stability and dependability has become a focal issue.

This from NREL:

The research involved hybrid halide perovskite solar cells and revealed treating them with a specific solution of methyl ammonium bromide (MABr) would repair defects, improving efficiency. The scientists converted a low-quality perovskite film with pinholes and small grains into a high-quality film without pinholes and with large grains. Doing so boosted the efficiency of the perovskite film in converting sunlight to 19 percent.
